How cold are we talking? How old is the car? Mileage? Most likely you are dealing with a battery, alternator, starter, solenoid, cables, look for dirty or loose connections, solenoid or maybe a fuse. If you can read a multimeter in voltage, you are ten minutes away from your answer. If you read the preceding post, you might be 15 seconds away from the answer. Civics of all vintages are simple in this regard, and in my experience, very few require new starters ever. I have owned several over the years and replaced one alternator and zero starters.
